What Causes Premature Graying in Dogs?

Learn study results for early graying in dogs.

Have you ever seen a young dog with a graying muzzle and wondered what caused it? A recent study has helped illuminate the reason why some dogs turn gray when they are as young as 1 year old.

Canine Early Graying

In a recent study (Camille King, 2016), 400 dogs between the ages of 1 and 4 were rated by researchers on the degree to which they had premature graying, from no gray to full gray. Light-colored dogs were not used in the study because it was too difficult to determine the degree to which they were gray.

Once the dogs were rated on grayness, the owners filled out questionnaires about them. The owners were not aware of the purpose of the study so they wouldn't answer the questions in a biased manner.

Questions about a dog's anxiety and impulsivity levels were included in the questionnaire as well as random distractor questions to keep the owner from guessing the purpose of the study.

The results of this study were that dogs that are fearful of loud noises, other animals, and people were much more prone to early graying than those dogs that were not afraid of such things. The authors stated, in conclusion, that "Premature graying in young dogs may be a possible indicator of anxiety, fear or impulsivity issues in dogs under [4] years of age (Camille King, 2016)."

What to Do If Your Young Dog Is Graying

If your dog is under 4 years of age and showing a graying muzzle, it would be a good idea to have him evaluated by your veterinarian or a veterinary behaviorist for fear, anxiety, and impulsivity behaviors.

Helping a dog with anxiety may include some or all of the following techniques:
